What is Plum?

Plum is a UK saving and investing app that uses artificial intelligence to analyse your spending and automatically set money aside. You connect your bank account via Open Banking (read-only access), and Plum's algorithm works out how much you can afford to save each week without affecting your day-to-day spending. Think of it as a financial autopilot: it moves small amounts into savings before you notice, and those small amounts add up surprisingly fast.

Beyond auto-saving, Plum offers a Cash ISA, a Lifetime ISA, a Stocks and Shares ISA, a self-invested personal pension (SIPP), and access to over 3,000 individual company stocks. The free plan covers the basics. Paid plans (from £2.99 per month) unlock higher interest rates, additional savings pockets, investing features and cashback. For a broader look at how Plum compares to other options, see our best apps to save money UK roundup.

How does the Plum referral code work?

There's no code to enter manually. The Plum referral code is built into the sign-up link on this page. When you tap the button and download the app, the referral is tracked automatically. Plum's referral programme runs periodically, and terms can change. At the time of writing, signing up via a referral link supports CoolCuration, and Plum occasionally offers new users a cashback bonus after meeting qualifying criteria (such as holding a minimum balance for 90 days). Always check the app for the latest offer when you sign up.

Plum savings rates (June 2026)

Plum offers several savings products, each with different rates and protections. Here's a snapshot of the current options.

Easy Access Savings Pocket: Up to 3.63% AER (variable). FSCS protected up to £120,000 via Investec Bank. Withdrawals are processed the same working day if requested by 3pm.

95-Day Notice Account: Up to 4.08% AER (variable). FSCS protected via Investec Bank. You need to give 95 days' notice before withdrawing.

Cash ISA: Up to 4.46% AER (variable) for new customers, including a 1.92% bonus rate for the first 12 months. After 12 months the rate drops to 2.54% AER. It is a flexible ISA, so you can withdraw and replace within the same tax year without using your allowance. Note that making more than four withdrawals in the bonus period, or letting the balance fall below £100, also drops the rate to 2.54% AER. Transfers in from another provider earn 4.00% AER for the first year. FSCS protected. Worth noting: from April 2027 the cash ISA allowance drops from £20,000 to £12,000 for savers under 65, so 2026/27 is the last full year at the higher limit.

Lifetime ISA: 4.70% AER (variable). For first-time buyers or retirement saving. The government adds a 25% bonus on contributions up to £4,000 per year (up to £1,000 free). A government withdrawal charge may apply if you withdraw for other purposes.

Plum Interest: Up to around 3.70%. This is a money market fund (BlackRock ICS Sterling Government Liquidity Fund), not a savings account. Capital is at risk, though the fund tracks close to the Bank of England base rate (currently 3.75%) after fees. This product is not FSCS protected.

Rates are correct as of June 2026 and may change. Always check the Plum app or Plum website for the latest rates.

Key features

Plum Brain (auto-saving)

This is a core Plum feature. The "Plum Brain" offers eight automated saving rules you can toggle on or off. These include round-ups (saving spare change from transactions), payday saves, a 52-week challenge, and the core AI auto-save that analyses your spending patterns. You set a "mood" from cautious to ambitious, and Plum adjusts how aggressively it saves. From our experience, even the moderate setting puts aside about £50 to £100 per month without you noticing.

Multiple savings goals

Plum lets you create separate savings pockets for different goals, so your holiday fund stays separate from your emergency buffer. On paid plans, you can open multiple interest-earning pockets with separate targets and visual progress trackers.

Investing

If you want to go beyond saving, Plum offers a Stocks and Shares ISA, a General Investment Account, and access to over 3,000 company stocks and 26 themed investment funds. You can start investing from just £1. However, investing carries risk, and you could get back less than you put in. Investing features require a paid plan.

Pension consolidation

Plum's self-invested personal pension (SIPP) lets you bring old workplace pensions together in one place and choose from a range of funds. This is useful if you've accumulated multiple small pension pots from different jobs over the years. Pension and investment values can fall as well as rise.

Plum plans and pricing

Plum offers one free plan and three paid plans. The free plan covers auto-saving, a primary pocket and access to the Cash ISA. Paid plans start at £2.99 per month and add features like investing, higher interest rates and cashback. All paid plans come with a 30-day free trial. If you're just getting started with saving, the free plan is a reasonable place to begin before deciding whether the paid features are worth it for you.

Is Plum safe?

Plum is regulated by the Financial Conduct Authority. Saveable Limited (trading as Plum) is FCA authorised (FRN 739214) for investment and credit broking. Plum Fintech Limited is FCA registered (FRN 836158) as an account information service provider.

However, not all Plum products carry the same level of protection. Money in savings pockets (held with Investec Bank) is FSCS protected up to £120,000 per person per banking licence. If you hold other deposits directly with Investec, those count towards the same £120,000 limit. The Cash ISA is held with Plum's partner banks (shown in the app), so the same shared-limit principle applies if you have existing accounts with those banks. Money in your primary pocket is held as e-money and is safeguarded under e-money regulations but is not FSCS protected. Plum Interest (the money market fund) is an investment product where your capital is at risk. For investment claims, FSCS protection is capped at £85,000 per person, not £120,000. For full details, see Plum's money protections page.

How Plum compares to Chip

Plum and Chip are two of the best-known auto-saving apps in the UK. On easy-access savings, Chip's boosted rate is currently higher, at up to 3.81% AER versus Plum's 3.63% AER. Plum offers a wider set of investment options, including a Lifetime ISA and a broader fund range. Chip's auto-save is free, and Plum's basic auto-save is free too, though some automation rules require a paid plan. Which one fits depends on whether your priority is the highest easy-access rate or having saving and investing together in one app. For more on Chip, see our Chip referral page.

Frequently asked questions

Is there a Plum referral code for new users?

The Plum referral code is embedded in the sign-up link on this page. You don't need to enter a code manually. Just tap the button, download the app, and the referral tracks automatically. Plum's referral programme runs periodically, so check the app after signing up for any current new user offers.

Is Plum free to use?

Yes. The basic plan is completely free and includes auto-saving, a primary savings pocket and access to the Cash ISA. Paid plans start at £2.99 per month and add features like investing, higher interest rates and cashback. All paid plans come with a 30-day free trial.

Is Plum FSCS protected?

Some Plum products are FSCS protected and others are not. Money held in savings pockets (provided by Investec Bank) is covered up to £120,000 per person per banking licence. If you already hold deposits with Plum's partner banks, those balances share the same £120,000 limit. Your primary pocket balance (held as e-money) is safeguarded but not FSCS protected. For investment products, FSCS protection is capped at £85,000 per person. Always check which product you're using and how your money is protected.

How much does Plum auto-save?

It depends on your spending patterns and the saving "mood" you select in the app. On moderate settings, most users save between £50 and £150 per month. You can pause, adjust or withdraw at any time. Plum will never save more than you can afford based on its analysis of your income and spending.

Can I use Plum for a Lifetime ISA?

Yes. Plum offers a Lifetime ISA at 4.70% AER (variable). You can save up to £4,000 per tax year and receive a 25% government bonus (up to £1,000). This is available for first-time buyers aged 18 to 39 saving for a home, or anyone saving for retirement. A government withdrawal charge applies if you withdraw for other purposes before age 60.

How does Plum compare to Monzo for saving?

Monzo offers savings pots built into your bank account, with rates that vary by plan and pot type (its instant access savings pays from around 2.75% to 3.25% AER depending on your Monzo plan). Plum is a standalone app that connects to any UK bank and adds AI-powered auto-saving on top. Monzo may suit those who want saving built into their banking, while Plum may suit those who want more automation and investment options regardless of who they bank with.
